2003-12-18Reverted back to previous revision - this was previously mergedJohn Criswell
according to the CVS log messages. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10517 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-18Merged in RELEASE_11.John Criswell
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10516 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-18Modify linear scan register allocator to use the two-addressAlkis Evlogimenos
instruction pass. This also fixes all remaining bugs for this new allocator to pass all tests under test/Programs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10515 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-18Fix bug in reserved registers. DH actually aliases DX and EDX whichAlkis Evlogimenos
are not reserved registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10514 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-18Modify local register allocator to use the two-address instruction pass.Alkis Evlogimenos
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10513 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-18Add TwoAddressInstructionPass to handle instructions that have two orAlkis Evlogimenos
more operands and the two first operands are constrained to be the same. The pass takes an instruction of the form: a = b op c and transforms it into: a = b a = a op c and also preserves live variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10512 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-18Rename LiveIntervals::expired() to LiveIntervals::expiredAt().Alkis Evlogimenos
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10511 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-18When a variable is killed and redifined in a basic block only oneAlkis Evlogimenos
killing instruction is tracked. This causes the LiveIntervals to create bogus intervals. The workaound is to add a range to the interval from the redefinition to the end of the basic block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10510 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-18Handle multiple virtual register definitions gracefully.Alkis Evlogimenos
Move some of the longer LiveIntervals::Interval method out of the header and add debug information to them. Fix bug and simplify range merging code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10509 91177308-0d34-0410-b5e6-96231b3b80d8

2003-12-18When we delete instructions from the loop, make sure to remove them from theChris Lattner
AliasSetTracker as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10507 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-18Add a new AliassetTracker::remove method. Because we need to be able to removeChris Lattner
a pointer from an AliasSet, maintain the pointer values on a doubly linked list instead of a singly linked list, to permit efficient removal from the middle of the list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10506 91177308-0d34-0410-b5e6-96231b3b80d8

2003-12-17Reorganized the Sparc backend to be more modular -- each differentMisha Brukman
implementation of a Target{RegInfo, InstrInfo, Machine, etc} now has a separate header and a separate implementation file. This means that instead of a massive SparcInternals.h that forces a recompilation of the whole target whenever a minor detail is changed, you should only recompile a few files. Note that SparcInternals.h is still around; its contents should be minimized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10500 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10462 91177308-0d34-0410-b5e6-96231b3b80d8
2003-12-14Change interface of MachineOperand as follows:Alkis Evlogimenos
a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse() b) add isUse(), isDef() c) rename opHiBits32() to isHiBits32(), opLoBits32() to isLoBits32(), opHiBits64() to isHiBits64(), opLoBits64() to isLoBits64(). This results to much more readable code, for example compare "op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used very often in the code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10461 91177308-0d34-0410-b5e6-96231b3b80d8
